Key Features
- 1 µF capacitance rated at 50 V with X7R dielectric for stable performance from -55°C to +125°C across industrial and automotive temperature ranges
- High-CV 0805 SMD form factor (3.2 mm × 1.6 mm × 1.25 mm) providing 1 µF in a compact, reliable surface-mount package
- RoHS-compliant (JESD-609 e3) lead-free construction meeting REACH compliance for global industrial and consumer applications
Applications
The UMK212B7105MG-T is widely used as a decoupling and bypass capacitor on 50 V power supply rails in industrial control boards, motor-drive inverters, and DC-DC converter output stages. Its X7R dielectric maintains capacitance within ±15% over the full -55°C to +125°C range, making it suitable for automotive ECU supply decoupling under AEC-Q200 screening criteria. Engineers also specify it for EMI filtering and bulk decoupling in power-over-Ethernet (PoE) and telecom power modules operating up to 50 V.

Frequently Asked Questions
What voltage and capacitance ratings does the Taiyo Yuden UMK212B7105MG-T carry?
The UMK212B7105MG-T is rated at 1 µF capacitance and 50 V DC working voltage with ±20% tolerance. The X7R dielectric ensures the capacitance remains stable within ±15% from -55°C to +125°C, making it suitable for demanding industrial and automotive decoupling tasks.
How does the X7R dielectric of the UMK212B7105MG-T perform under temperature variation compared to Y5V types?
The X7R dielectric limits capacitance change to ±15% over the full -55°C to +125°C range, whereas Y5V types can vary by -82% to +22% over a narrower span. For a 1 µF, 50 V decoupling capacitor operating in an automotive ECU, the X7R stability is far superior to Y5V.
Can the UMK212B7105MG-T be used on 48 V automotive bus rails or is it limited to 12 V systems?
With a 50 V working voltage rating, the UMK212B7105MG-T can be used on 48 V automotive mild-hybrid bus rails, provided that voltage spikes and transients stay below the 50 V limit. A derating of 80% is recommended, so the effective continuous operating voltage should not exceed 40 V on a live 48 V bus.
