Key Features

• Conductive polymer aluminum construction Solid electrolyte provides low ESR and stable performance across temperature and frequency.
• Electrical ratings 12 µF capacitance with a rated voltage of 50 V and tolerance ±20% at 120 Hz, 20°C.
• Low ESR and loss ESR specified at 40 mΩ (measured at 100 kHz, 20°C) and tan δ of 0.12 (20°C, 120 Hz) for efficient high‑frequency performance.
• High ripple capability Ripple current ratings of 110 mA at 120 Hz and 1.1 A at 300 kHz allow sustained AC stress handling in power circuits.
• Extended high‑temperature endurance Load life specified at 3,000 hours at 125°C, with endurance limits for capacitance, tan δ and ESR stated in the series datasheet.
• Robust operating range and solder compatibility Operating temperature −55°C to +125°C; compatible with lead‑free reflow soldering up to a 260°C peak as specified for the series.
• Compact SMD package Radial can SMD format, dimensions φ6.3 × 7.7 mm with recommended land size 6.6 × 6.6 mm for PCB layout and space‑constrained designs.
• Leakage current Leakage current specified at 100 µA (after standard voltage application), supporting predictable standby and bias behavior.
• RoHS compliance (series) Series documentation indicates compliance with RoHS directives per the datasheet.

Typical Applications

• Power supply decoupling — Low ESR and high high‑frequency ripple capability make this part suitable for smoothing and decoupling on DC‑DC converter outputs and regulator outputs.
• Switch‑mode power supplies — High allowable ripple current and compact SMD package support energy storage and filtering in compact SMPS boards.
• Industrial electronics — Extended 125°C endurance and broad operating temperature range support demanding thermal environments and long‑life deployments.
• High‑frequency filtering — Specified ESR at 100 kHz and measured ripple ratings enable effective HF bypassing in mixed‑signal and power distribution networks.

Unique Advantages

• Low ESR for efficient power handling: 40 mΩ at 100 kHz reduces dissipation in high‑frequency applications and improves voltage stability under ripple.
• High ripple current capability: Rated for 1.1 A at 300 kHz and 110 mA at 120 Hz, enabling reliable operation under AC stress without premature degradation.
• High‑temperature longevity: 3,000‑hour load life at 125°C provides predictable ageing and long service life in thermally demanding systems.
• Compact footprint: φ6.3 × 7.7 mm SMD can balances capacitance and voltage with minimal PCB area for space‑constrained designs.
• Reflow compatible: Designed for lead‑free reflow up to 260°C peak as specified for the series, supporting modern assembly processes.
• Controlled leakage and loss characteristics: Specified leakage current (100 µA) and tan δ (0.12) give designers predictable bias and dissipation parameters.
