Murata Electronics GRM155R61E105KA12D

Overview

GRM155R61E105KA12D from Murata is a multilayer ceramic capacitor designed for compact board-level decoupling, filtering, energy buffering, and signal-conditioning roles in dense electronic assemblies. This MLCC combines a 1μF nominal capacitance, 25V rated voltage, X5R dielectric system, ±10% tolerance, and 0402-size package footprint, making it suitable for AI server motherboards, accelerator cards, storage modules, networking hardware, and other high-density digital or mixed-signal platforms where ceramic stability and footprint efficiency matter.

The selected X5R dielectric, -55~+85°C operating-temperature class, and package size give GRM155R61E105KA12D a design profile aligned with high-density decoupling or filtering tasks where board area, impedance behavior, and rail stability are important. For engineers reviewing the GRM155R61E105KA12D datasheet, GRM155R61E105KA12D pinout, GRM155R61E105KA12D application, or GRM155R61E105KA12D equivalent, this device is widely used in power-rail decoupling, point-of-load output filtering, control-plane support networks, storage and networking modules, and compact high-speed embedded hardware.

Applications

Equivalent & Alternatives

When evaluating a GRM155R61E105KA12D equivalent, engineers should compare capacitance, package size, rated voltage, dielectric class, tolerance, temperature range, and actual board role before substitution.

Compared with JMK316BJ105KL-T and JMK325BJ105KH-T, GRM155R61E105KA12D should be selected according to the exact capacitance, package, voltage rating, dielectric behavior, tolerance, and temperature-class needs of the target board location. Substitution decisions for MLCCs should also consider DC-bias behavior, effective capacitance under load, and placement role on the rail or signal path.

Quality

GRM155R61E105KA12D should be sourced as original branded MLCC inventory through traceable supply channels. Quality checks may include package inspection, marking and reel-label verification, solderability review, and lot-level handling controls appropriate for ceramic capacitors.

Production validation should include capacitance verification where needed, board-level placement review, reflow-process compatibility, and local rail or signal-integrity confirmation in the final mounted application.

Availability

GRM155R61E105KA12D is suitable for AI server, accelerator, storage, networking, and high-density embedded hardware that needs compact MLCC support for decoupling, filtering, or local energy storage.

Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming capacitance, package size, dielectric class, rated voltage, tolerance, temperature range, lifecycle status, and sourcing continuity helps reduce passive-component procurement risk.
