PLF1D121MCL2

The PLF1D121MCL2 is a radial lead conductive polymer aluminum electrolytic capacitor offering 120 µF capacitance at a 20 V rating. Its solid polymer chemistry delivers low ESR and high ripple-current capability in a compact φ10 × 10 mm can with 5 mm lead spacing.

Designed and qualified to AEC‑Q200 with RoHS compliance and a rated operating range of −55 °C to 105 °C, the PLF1D121MCL2 targets harsh-environment and automotive electronic power applications. Note: this part is not recommended for new designs.

Key Features

• Electrical Performance — 120 µF capacitance with ±20% tolerance (measured at 120 Hz, 20 °C) and a tan δ of 0.12 (20 °C, 120 Hz, 20 V) for predictable frequency response.
• Low ESR and High Ripple Handling — ESR of 35 mΩ at 20 °C/100 kHz, supporting 1.4 A ripple at 120 Hz and 2.8 A ripple at 100 kHz to handle both low- and high-frequency ripple currents.
• Reliability & Endurance — Load life rated to 2000 hours at 105 °C; endurance specifications ensure capacitance, tan δ and ESR remain within defined limits after life testing.
• Automotive-Grade Qualification — AEC‑Q200 qualified and specified for an operating temperature range of −55 °C to 105 °C, suitable for temperature-extreme environments.
• Package & Mounting — Radial lead, polarized can in φ10 × 10L size with 5 mm lead spacing (±0.5 mm); available in bulk or bag packing for through-hole assembly workflows.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive power electronics — Suitable for in-vehicle modules that require AEC‑Q200 qualification and components capable of handling high ripple currents and wide temperature ranges.
• Power conversion and smoothing — Low ESR and measurable ripple-current ratings at both 120 Hz and 100 kHz make this capacitor appropriate for filtering and smoothing in power supplies and DC–DC converters.
• Harsh-environment electronics — Rated for −55 °C to 105 °C and 2000 h endurance at 105 °C, fitting applications exposed to wide temperature ranges and demanding duty cycles.

Unique Advantages

• High ripple-current capability: Specified 1.4 A (120 Hz) and 2.8 A (100 kHz) ripple ratings reduce thermal stress and support reliable performance under dynamic loads.
• Low ESR for thermal efficiency: 35 mΩ ESR at 100 kHz lowers internal heating and improves power efficiency in high-frequency applications.
• AEC‑Q200 qualification: Provides the documented reliability expectations needed for automotive and similarly demanding electronic systems.
• Compact radial package: φ10 × 10 mm can with 5 mm lead spacing offers compact through-hole mounting for legacy boards or high-reliability assemblies.
• Proven endurance: 2000 hours at 105 °C ensures stable capacitance, tan δ and ESR characteristics over extended high-temperature operation.
• Regulatory compliance: RoHS compliance supports regulatory and environmental requirements.
