Key Features

• Capacitance and Voltage — 12 µF nominal capacitance at a rated voltage of 63 V with ±20% tolerance.
• Low ESR — 51 mΩ equivalent series resistance measured at 100 kHz, enabling efficient high-frequency decoupling.
• High Ripple Current — Handles up to 1 A at 100 kHz (and 500 mA at 120 Hz) for demanding power-supply filtering.
• High‑Temperature Operation — Rated for continuous operation from -55 °C to 125 °C, with endurance specified at elevated temperature.
• Long Life — Lifetime specified as 6000 hours at 125 °C for the φD = 6.3 mm case.
• Automotive Reliability — AEC‑Q200 qualified for applications requiring automotive-grade component qualification.
• SMD Can Package — Compact chip-type radial can designed for surface-mount assembly; size L: 6 × D: 6.3 mm with recommended land size L: 6.6 × W: 6.6 mm.
• Lead‑Free Reflow Compatible — Conforms to lead‑free reflow soldering condition at a 260 °C peak (pre‑heat and profile requirements apply).
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Local decoupling and filtering in automotive control modules and sensor interfaces where AEC‑Q200 qualification and wide temperature range are required.
• Power Conversion — Input/output smoothing and bulk decoupling in DC‑DC converters and power-supply modules that require high ripple-current handling and low ESR.
• High‑Temperature Electronics — On-board power filtering in systems operating at elevated ambient temperatures up to 125 °C.

Unique Advantages

• Reliable high-temperature endurance — Specified for 6000 hours at 125 °C (φD = 6.3 mm), supporting long-term operation in hot environments.
• Low-loss, high-frequency performance — 51 mΩ ESR at 100 kHz provides effective high-frequency decoupling and reduced power loss.
• Robust ripple-current capability — Rated for up to 1 A at 100 kHz, enabling tighter regulation and stable operation in power stages.
• Automotive‑ready qualification — AEC‑Q200 qualification supports use in vehicle electronics and other high-reliability applications.
• Surface-mount can for compact layouts — Small 6 × 6.3 mm footprint and SMD mounting simplify PCB integration and BOM consolidation.
• Manufacturing-friendly soldering — Compatible with lead-free reflow profiles up to 260 °C peak for modern assembly processes.
