PCH1H390MCL1GS

The PCH1H390MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for demanding, high-temperature environments. It delivers low ESR and high ripple-current capability in a compact surface-mount can package optimized for reliable power filtering and decoupling.

Targeted at automotive and other high-reliability markets, this AEC-Q200 qualified capacitor supports operation from –55 °C to +135 °C and is rated for 50 V with a 39 µF capacitance, providing long life and stable performance where temperature and endurance matter.

Key Features

• Electrical Performance — 39 µF capacitance at a 50 V rating with ±20% tolerance, providing stable charge storage for power rails and decoupling applications.
• Low ESR & High Ripple Current — ESR of 45 mOhm (measured at 100 kHz) with ripple current capability up to 900 mA at 100 kHz (450 mA at 120 Hz), enabling efficient power delivery and reduced dissipation.
• High Temperature Operation — Rated for continuous operation from –55 °C to +135 °C, with endurance specified for 4000 hours at 135 °C for long-term reliability in hot environments.
• Reliability & Qualification — AEC-Q200 qualified and designed to meet endurance, damp heat, and shelf-life criteria defined in the product datasheet; ESR retention is demonstrated after endurance tests (measured at –40 °C).
• Surface-Mount Can Package — Compact chip-type radial can SMD (L: 7 × D: 8 mm) with recommended land size 8.3 × 8.3 mm for PCB layout efficiency.
• Assembly Compatibility — Compatible with lead-free reflow soldering conditions up to a 260 °C peak as specified, supporting modern RoHS-compliant assembly processes.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power electronics — Power rail decoupling and filtering in automotive modules that require AEC-Q200 qualification and high-temperature endurance.
• DC–DC converters and power modules — Low ESR and high ripple-current capability make this capacitor suitable for smoothing and output filtering in compact power supplies.
• Under-hood and harsh-environment electronics — Long 4000-hour life at 135 °C and wide operating temperature range support deployments in high ambient temperature locations.

Unique Advantages

• High-temperature endurance: Specified 4000 hours at 135 °C for predictable lifetime and maintenance planning in hot operating conditions.
• Low dissipation in confined spaces: 45 mOhm ESR at 100 kHz reduces power loss and thermal stress in compact SMD can format.
• Designed for high ripple environments: 900 mA ripple current rating at 100 kHz minimizes voltage ripple and improves regulator stability.
• Automotive-grade qualification: AEC-Q200 rating confirms suitability for designs requiring standardized automotive reliability testing.
• Lead-free assembly ready: Compatibility with 260 °C peak lead-free reflow supports RoHS-compliant manufacturing flows.
