GRM188R61E106KA73D Murata MLCC Selection Guide

GRM188R61E106KA73D Murata MLCC is a 10 uF, 25V, X5R, +/-10%, 0603 MLCC used for local decoupling, bypassing and rail stabilization in compact electronic assemblies. Engineers should review the effective capacitance, voltage derating, dielectric behavior, package size and sourcing path before placing it into a released BOM. Search In-Fortune for GRM188R61E106KA73D or contact In-Fortune for sourcing support while the exact product detail page is confirmed.

What is GRM188R61E106KA73D?

GRM188R61E106KA73D is a Murata GRM-series surface-mount multilayer ceramic capacitor. It is a passive, two-terminal, non-polarized component, so its practical pinout is the pad geometry, solder fillet and package orientation on the PCB rather than a numbered IC pin map. The part is normally selected by capacitance, rated voltage, dielectric, tolerance, case size, thickness and application category.

The headline value is 10 uF, 25V, X5R, +/-10%, 0603 MLCC, but MLCC selection cannot stop at the nameplate capacitance. High-K ceramic capacitors lose effective capacitance under DC bias, temperature change and aging. For regulator outputs, processor rails, RF modules or sensor supplies, the design team should calculate the required effective capacitance at the actual rail voltage and then validate ripple, transient response and startup behavior on the real board.

Product-page note: no exact In-Fortune product detail URL for GRM188R61E106KA73D was found in the checked local product-link index or public site search. The article therefore links the exact model text to the In-Fortune model search and RFQ path until a confirmed detail page is available.

How GRM188R61E106KA73D is used

Typical circuit role

Most designs use GRM188R61E106KA73D between a supply rail and ground near an IC power pin, regulator output, load-switch output, connector input or module supply node. The capacitor provides a local current path during fast load changes and lowers high-frequency rail impedance. In a power tree it may be used together with smaller 0.1 uF or 1 uF capacitors and larger bulk capacitors, but each value should have a clear role instead of being copied from a reference design without review.

For decoupling, place the capacitor close to the load, keep the loop area small, and avoid long narrow traces that add inductance. For regulator output use, check the regulator datasheet for allowable output-capacitor value, ESR range and stability requirements. If the rail sees repetitive pulse current, review heating, acoustic noise risk, board flex and the number of capacitors needed in parallel.

Layout and assembly notes

The 0603 (1608 metric) package should match the PCB land pattern and assembly process. Small MLCCs are non-polarized, but they can still crack if the board bends or if the land pattern creates uneven stress. Avoid placing the part across major bend lines, review the reflow profile and confirm nearby thermal mass does not create tombstoning or weak solder joints. If the design is safety, automotive or medical related, confirm the required Murata product category and customer approval path before using a general-purpose GRM part.

Key specifications for GRM188R61E106KA73D

GRM188R61E106KA73D selection guide

Select GRM188R61E106KA73D when the design needs 10 uF nominal capacitance, 25V rated voltage, X5R temperature characteristic and the 0603 (1608 metric) footprint. It is a reasonable candidate for space-constrained 25V rails that need 10 uF nominal capacitance in a 0603 footprint. In a sourcing or redesign discussion, keep the full part number intact because suffix characters can affect packaging, dimensions, reliability documentation and purchasing handling.

Do not select GRM188R61E106KA73D when the design needs a higher effective capacitance after DC bias than this package can provide, a higher voltage rating, a different temperature range, a lower-profile package or a formally qualified part for a different application class. It is also not a direct substitute for another capacitor just because the capacitance looks similar. Package size, dielectric, ESR, impedance curve, thickness and reliability category can change the circuit result.

If the design condition matches high-pulse or high-temperature positions where a larger case, higher voltage rating or different dielectric is needed, review a different Murata value, a larger case size, a higher voltage rating, a polymer capacitor, or a combination of MLCCs and bulk capacitors. Engineering should document the minimum effective capacitance target and procurement should document which substitutes are acceptable.

Alternatives and cross references for GRM188R61E106KA73D

Alternatives are useful for continuity planning, but MLCC replacements can fail quietly if only capacitance and voltage are compared. Before approving a GRM188R61E106KA73D replacement, compare the datasheet, dielectric, rated voltage, tolerance, package, thickness, PCB footprint, land pattern, DC-bias curve, impedance behavior, temperature range, lifecycle status, application category and customer approval requirements.

Buying notes and sourcing checks

Before issuing an RFQ for GRM188R61E106KA73D, confirm the full Murata part number, capacitance, rated voltage, tolerance, dielectric, package case, thickness, packaging method, date-code expectation, lot consistency, original factory condition, traceability documents, RoHS or REACH needs, delivery schedule and accepted substitute range. Do not shorten the request to only the capacitance and voltage; that loses the mechanical and dielectric details that control the design risk.

Ask the supplier to confirm whether the offered part matches the requested suffix and whether the reel code is acceptable for the SMT process. Request sourcing support for GRM188R61E106KA73D. Contact In-Fortune to confirm GRM188R61E106KA73D specifications. Send an RFQ with your required quantity and delivery schedule, and state whether same-value alternatives are acceptable or engineering-approved only.

GRM188R61E106KA73D FAQ

Where can I find the GRM188R61E106KA73D datasheet?

Start with the Murata product data page and the In-Fortune article or product-search path for GRM188R61E106KA73D. The latest approval sheet and packaging code should be confirmed with supplier before production use.

What is the GRM188R61E106KA73D pinout?

GRM188R61E106KA73D is a two-terminal, non-polarized MLCC. The pinout check is the PCB land pattern, package size, soldering geometry and placement clearance.

What applications fit Murata GRM188R61E106KA73D?
