Key Features
- 1 µF capacitance with X7R dielectric and 50 V DC voltage rating in a compact 0805 (2.0 mm × 1.25 mm) surface-mount package for decoupling and filtering
- ±10% capacitance tolerance with stable X7R temperature characteristic (-55°C to +125°C, ≤±15% capacitance change) ensures reliable performance across operating temperature extremes
- AEC-Q200-qualified automotive-grade construction with RoHS and REACH compliance for use in vehicle electronics and high-reliability industrial equipment
Applications
The GCJ21BR71H105KA01L is used as a bulk bypass and decoupling capacitor on power supply rails in automotive ECU modules, industrial motor drives, and consumer electronics where a 50 V rated 1 µF MLCC is required for noise filtering. Its X7R dielectric provides stable capacitance across the -55°C to +125°C automotive temperature range, making it suitable for under-hood and dashboard control unit applications. The 0805 footprint allows direct drop-in replacement of equivalent 1 µF MLCC capacitors in both new designs and legacy board revisions.

Frequently Asked Questions
What is the voltage rating and capacitance of the GCJ21BR71H105KA01L, and how does the X7R dielectric affect stability?
The GCJ21BR71H105KA01L provides 1 µF capacitance at a rated voltage of 50 V DC with ±10% tolerance. The X7R dielectric maintains capacitance within ±15% of nominal across the full -55°C to +125°C temperature range, making it significantly more stable than Y5V capacitors and well-suited for precision bypass and filtering circuits in automotive and industrial power systems.
Which automotive or industrial applications benefit most from the GCJ21BR71H105KA01L's 50 V and 1 µF combination?
A 50 V rated 1 µF MLCC is ideally suited for decoupling power supply rails in 12 V to 48 V automotive systems, such as ECU power stages, motor control gate drivers, and CAN bus transceiver supply pins. The 50 V rating provides a 4× derating margin on a 12 V rail, improving long-term reliability in automotive electronics where voltage spikes of 25 V to 40 V are common during load dump events.
How does the 0805 package size of GCJ21BR71H105KA01L compare to a 0603 alternative for the same 1 µF / 50 V rating?
Achieving 1 µF at 50 V in a 0603 package is physically challenging due to dielectric thickness requirements, so most 0603 MLCCs at this voltage rating are limited to 0.1 µF or 0.47 µF. The 0805 package (2.0 mm × 1.25 mm) of the GCJ21BR71H105KA01L provides the extra dielectric layers needed to reach 1 µF at 50 V, making it the practical minimum package size for this capacitance-voltage combination in X7R ceramic capacitors.
