PCH1E681MCL1GS

The PCH1E681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount assemblies that require high capacitance and robust high-temperature performance. It delivers 680 µF at 25 V in a compact SMD can package and is built for applications requiring low ESR, high ripple handling and long-term stability at elevated temperatures.

Targeted market segments include automotive and other high-reliability electronics where wide temperature range operation, AEC‑Q200 qualification and lead-free reflow compatibility are important design considerations.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low ESR & High Ripple Capacity — ESR of 14 mΩ measured at 100 kHz and ripple current capability of 3.1 A at 100 kHz (1.55 A at 120 Hz), supporting high-frequency power decoupling and smoothing.
• High-Temperature Endurance — Long life rating of 4000 hours at 135°C, with specified endurance characteristics for capacitance, tan δ, ESR and leakage current after test.
• Wide Operating Temperature — Rated for operation from −55°C to +135°C, suitable for electronics exposed to wide ambient ranges.
• SMD Package & Reflow Compatibility — Chip-type SMD can in a compact footprint (L: 1.6 × D: 1.0 cm) and compatible with lead-free reflow soldering (260°C peak profile compliance).
• Automotive-Grade Qualification — AEC‑Q200 qualified for applications requiring automotive-level component qualification.

Typical Applications

• Automotive Electronics: Power decoupling and smoothing in control modules and electronic systems where AEC‑Q200 qualification and high-temperature endurance are required.
• High-Temperature Electronics: Circuits that operate in elevated ambient conditions up to 135°C, benefiting from the capacitor's long life at temperature.
• Compact Surface-Mount Power Designs: Space-constrained SMD assemblies needing high capacitance and low ESR for high-frequency power delivery and stability.

Unique Advantages

• High capacitance in a compact SMD can: 680 µF in a 1.6 × 1.0 cm package reduces board area compared with larger radial options.
• Low ESR at high frequency: 14 mΩ at 100 kHz enables better voltage stability and reduced losses in high-frequency power stages.
• High ripple handling: Rated ripple currents up to 3.1 A at 100 kHz support demanding switching power applications.
• Long-term high-temperature reliability: 4000 hours endurance at 135°C provides predictable performance in thermally aggressive environments.
• Automotive-grade qualification: AEC‑Q200 status supports use in automotive and other reliability-focused programs.
• Lead-free reflow compatible: Conforms to lead-free reflow soldering conditions up to a 260°C peak, easing integration into modern SMT assembly flows.
