Product Overview

GRM155R71H104KE14D is an ultra-small general-purpose Multi-layer Ceramic Capacitor (MLCC) launched by Murata Manufacturing, tailored for high-density electronic devices requiring space-saving and stable performance. It adopts the 0402 inch package (1005mm, L1.0±0.05mm×W0.5±0.05mm×T0.5±0.05mm), equipped with X7R dielectric material (EIA standard, corresponding to temperature characteristic code R7), with a rated capacitance of 0.1μF (100nF), rated voltage of DC 50V, and capacitance tolerance of ±10%. The termination uses lead-free Ni/Cu/Sn plating, fully complying with RoHS 2.0 and REACH directives.

With a wide operating temperature range of -55℃~125℃ and capacitance change ≤±15% in the full temperature domain, it passes strict reliability tests (voltage resistance, vibration, high-temperature humidity, etc.) and is compatible with reflow soldering processes. Widely used in smartphone RF modules, smart wearables, small IoT terminals, and industrial micro-sensors, it is a core capacitor solution balancing miniaturization, temperature stability, and high-voltage adaptability.

Key Features

• Ultra-Small 0402 Package for Space Saving: Adopts the 0402 inch (1005mm) package with dimensions of only 1.0mm×0.5mm×0.5mm, reducing the mounting area by 56% compared to the 0603 package. It is ideal for high-density PCB designs in smartphones, smart watches, and other miniaturized devices, supporting integration of more components.
• Wide Temperature Stability with X7R Material: Equipped with X7R dielectric material, the operating temperature range covers -55℃~125℃, and the capacitance change within this range is ≤±15%. It can withstand low temperatures in outdoor winter (-30℃ below) and local high temperatures during device operation (over 100℃), adapting to consumer electronics, industrial, and automotive non-safety scenarios.
• High Rated Voltage of 50V for Shock Resistance: With a rated voltage of DC 50V, it far exceeds the conventional 25V specification of the same package, capable of withstanding instantaneous high-voltage shocks in circuits (such as power switches and electrostatic discharge). It is suitable for industrial sensor power supplies and automotive USB interfaces that require high voltage reserves, eliminating the need for additional voltage protection circuits.
• Lead-Free Compliance & Full Process Compatibility: The termination adopts a lead-free Ni/Cu/Sn structure, compatible with Sn-3.0Ag-0.5Cu lead-free solder, complying with RoHS 2.0 and REACH regulations; it supports reflow soldering (peak 240~260℃/10±0.5s), highly compatible with SMT automated production lines, with a placement yield ≥99.8%.
• Flexible Bulk Packaging for Multi-Capacity Needs: Three packaging specifications are available: φ180mm (20,000pcs/reel, W8P1 paper tape), φ180mm (10,000pcs/reel, W8P2 paper tape), and φ330mm (50,000pcs/reel, W8P2 paper tape), adapting to small-batch trial production, medium-batch production, and large-scale mass production respectively, reducing inventory and material management costs.

Typical Applications

• Smartphones & RF Modules: Suitable for RF front-end filtering circuits of 5G smartphones. The ultra-small 0402 package of GRM155R71H104KE14D adapts to high-density motherboard layouts, the 0.1μF capacitance accurately filters RF signal noise, the X7R wide-temperature characteristic withstands local high temperatures (≤100℃) during phone charging, and the 50V voltage copes with instantaneous high voltage in RF circuits.
• Smart Wearables: Used in power management and sensor signal conditioning circuits of smart bracelets and watches. The ultra-small size of 1.0mm×0.5mm can be embedded in the narrow space of wearable devices, the -55~125℃ temperature range covers outdoor low temperatures and device operation high temperatures, and the 0.1μF capacitance stably stores energy to extend device battery life.
• Small IoT Terminals: Adapted to Bluetooth gateways and micro-sensors (such as temperature-humidity sensors and light sensors). The lead-free environmental protection feature complies with IoT device export requirements, the 50V rated voltage adapts to battery power supply and external power switching scenarios, and the wide-temperature characteristic copes with indoor and outdoor temperature differences.
• Industrial Micro-Sensors: Used in signal coupling circuits of small industrial sensors (pressure, displacement). The X7R material withstands temperature fluctuations of -20℃~85℃ in industrial workshops, the insulation resistance ≥50MΩ·μF reduces leakage risks to ensure accurate sensor data collection, and the 0402 package adapts to sensor miniaturization design.
• Consumer Electronics Accessories: Used in power filtering circuits of Bluetooth headsets and micro home appliances (mini humidifiers, portable juicers). The ultra-small package saves internal device space, the 50V voltage adapts to instantaneous high voltage of charging modules, the lead-free feature complies with global consumer electronics environmental standards, and it has high long-term reliability.
