PLS1C331MDO1

The PLS1C331MDO1 is a radial‑lead conductive polymer aluminum solid electrolytic capacitor offering 330 µF capacitance at a 16 V rating. It combines ultra‑low ESR and high ripple current capability in a compact φ10 × 13 mm can for general‑purpose electronic applications.

Engineered for long life, the device is specified for 5000 hours at 105°C and operates across a wide temperature range of −55°C to +105°C, making it suitable where long endurance, low loss and robust ripple handling are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 16 V.
• Ultra‑low ESR — ESR specified at 9 mΩ (100 kHz, 20°C), supporting efficient high‑frequency performance.
• High ripple current capability — Low‑frequency ripple current of 2.35 A (120 Hz) and high‑frequency ripple current of 4.7 A (100 kHz).
• Long life endurance — Rated load life of 5000 hours at 105°C with defined limits for capacitance change, tan δ and ESR after test.
• Temperature range & stability — Operating range −55°C to +105°C with impedance characteristics specified across that range.
• Low loss characteristics — tan δ (DF) of 0.08 measured at 20°C, 120 Hz for low dissipation in AC applications.
• Form factor & mounting — Radial lead package (φ10 × 13L) with 5 mm lead spacing and bulk or bag packing options.
• Leakage current — Specified leakage current of 1056 µA after rated voltage application conditions.
• RoHS compliant — Meets RoHS directive requirements as specified.

Typical Applications

• Power‑rail decoupling — Low ESR (9 mΩ) and high high‑frequency ripple current (4.7 A) help stabilize and decouple 16 V power rails in compact electronic designs.
• Bulk energy storage on PCBs — 330 µF capacitance in a φ10 × 13 mm radial can provides board‑level bulk capacitance where long endurance and compact size are required.
• Switching power supplies and converters — Specified ripple current and low tan δ (0.08 at 120 Hz) support efficient suppression of switching noise and thermal performance under load.

Unique Advantages

• Low thermal loss: The low tan δ value (0.08 at 20°C, 120 Hz) minimizes dissipation under AC stress, reducing self‑heating during operation.
• High ripple handling: Combined low ESR and rated ripple currents enable reliable performance in both low‑ and high‑frequency ripple environments.
• Long operational life: 5000‑hour endurance at 105°C provides predictable long‑term performance for designs requiring extended reliability.
• Compact radial package: φ10 × 13 mm can with 5 mm lead spacing delivers a space‑efficient solution for board‑level bulk and smoothing applications.
• Specification transparency: Key parameters such as ESR, ripple current, leakage current and tan δ are explicitly specified, allowing direct thermal and lifetime trade‑offs in design.
• RoHS compliance: Conformance to RoHS directives supports use in lead‑free manufacturing environments.
