PLV1D221MDL1

The PLV1D221MDL1 is a 220 µF, 20 V conductive polymer aluminum electrolytic capacitor in a radial lead can package. It is part of Nichicon's PLV series of solid electrolytic capacitors designed for low ESR, high ripple current handling and long-life operation.

This part targets power-conditioning roles in electronics where low equivalent series resistance, elevated temperature endurance and through-hole mounting are required. The PLV series supports high voltage options up to 100 V and is designed for demanding environments, including automotive applications where AEC‑Q200 compliance is required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 20 V, with ±20% tolerance for standard decoupling and smoothing applications.
• Conductive Polymer Electrolyte — Solid polymer construction provides low ESR and stable performance for high-frequency and high-ripple environments.
• Low ESR — 25 mΩ equivalent series resistance specified at 100 kHz, enabling effective high-frequency filtering and reduced power loss.
• High Ripple Current — Rated ripple current of 1.2 A at 120 Hz and 2.4 A at 100 kHz to support switching regulator and power-supply loads.
• Long Life at Elevated Temperature — Endurance specification of 3000 hours at 105°C, with capacitance and ESR limits defined for post-test recovery.
• Wide Temperature Range — Operates from –55°C to +105°C, suitable for thermally demanding applications.
• Radial Lead Package — Through-hole radial can with 3.5 mm lead spacing and overall size L: 1.2 × D: 0.8 cm; compatible with lead‑free flow soldering conditions.
• Automotive-Grade Reliability — AEC‑Q200 compliant and RoHS‑compliant to support regulated markets.

Typical Applications

• Power supply decoupling — Low ESR (25 mΩ at 100 kHz) and high ripple capability (2.4 A at 100 kHz) make this capacitor suitable for smoothing and decoupling in switching regulator outputs and DC‑DC converters.
• Automotive electronics — AEC‑Q200 compliance and a temperature range of –55°C to +105°C support use in control modules, sensor interfaces and actuator driver circuits.
• High-frequency filtering — The conductive polymer construction and specified ESR at 100 kHz provide reliable high‑frequency noise suppression for signal and power rails.
• Industrial power systems — Long life (3000 hours at 105°C) and robust ripple handling suit industrial controllers and power-conditioning assemblies operating under elevated thermal stress.

Unique Advantages

• Low-loss performance: The 25 mΩ ESR at 100 kHz reduces dissipation and improves efficiency in high-frequency power circuits.
• High ripple tolerance: Rated ripple currents of 1.2 A (120 Hz) and 2.4 A (100 kHz) enable reliable handling of switching and pulse loads.
• Thermal endurance: 3000 hours at 105°C provides predictable aging characteristics for designs exposed to sustained high temperatures.
• Automotive-capable: AEC‑Q200 compliance supports deployment in automotive-grade electronics and related regulated applications.
• Through-hole convenience: Radial lead can with 3.5 mm lead spacing and lead‑free flow soldering compatibility simplifies assembly for legacy and repairable designs.
• Regulatory compliance: RoHS conformity ensures suitability for markets with hazardous-substance regulations.
