PCH1C681MCL1GS

The PCH1C681MCL1GS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s PCH series, offering 680 µF capacitance at a 16 V rating. It is built for high-temperature, high-ripple environments where low ESR and long endurance are required.

Key attributes include low ESR (19 mΩ at 100 kHz, 20°C), high ripple-current capability (1.15 A at 120 Hz and 2.3 A at 100 kHz), a wide operating temperature range (−55°C to +135°C), and a rated life of 4000 hours at 135°C.

Key Features

• Dielectric and Construction Conductive polymer aluminum solid electrolyte in a chip-type SMD can for reliable solid-electrolyte performance.
• Capacitance & Voltage 680 µF nominal capacitance with tolerance −20% to +20% at a 16 V rated voltage.
• Low ESR & Tangent Loss ESR of 19 mΩ measured at 100 kHz, 20°C and tan δ of 0.08 at 120 Hz, 20°C, supporting efficient power filtering and low dissipation.
• High Ripple Current Handling Low-frequency ripple current 1.15 A (120 Hz) and high-frequency ripple current 2.3 A (100 kHz) for demanding power-rail decoupling.
• Wide Temperature & Long Endurance Operating temperature −55°C to +135°C with endurance specified as 4000 hours at 135°C; after endurance, capacitance remains within ±20% and ESR within 200% of initial.
• SMD Package & Dimensions Compact radial can SMD: φ10 × 10 L (1.0 × 1.0 cm), surface-mount land size 1.03 × 1.03 cm, packaged in embossed carrier taping with moisture-proof packing.
• Reflow Compatibility Compatible with lead‑free reflow soldering conditions up to a 260°C peak (measurement and cycle limits per datasheet).
• Leakage Current Specified leakage current 326 µA (measured condition per product data).
• Qualification & Compliance AEC-Q200 rated and RoHS compliant, suitable where recognized component qualification and environmental compliance are required.

Typical Applications

• Automotive Power Rails Local decoupling and energy buffering for control modules and sensor interfaces that require wide temperature operation and AEC-Q200 qualification.
• DC–DC Converters Output filtering and bulk smoothing where low ESR and high ripple-current capability improve regulator efficiency and transient response.
• Industrial Control Electronics Power conditioning in high-temperature industrial environments where endurance at 135°C and stable capacitance over time are critical.
• Telecom and Network Power Modules Smoothing and decoupling in compact SMD power assemblies that demand compact footprint with high ripple handling.

Unique Advantages

• Low ESR for Efficient Power Delivery: 19 mΩ at 100 kHz (20°C) reduces voltage drop and power loss on high-current rails.
• High Ripple Capability: Rated ripple currents of 1.15 A (120 Hz) and 2.3 A (100 kHz) support both low- and high-frequency noise suppression.
• Extended High‑Temperature Endurance: 4000 hours at 135°C with controlled changes to capacitance and ESR for reliable long-term operation.
• Compact SMD Can: φ10 × 10 mm package and embossed carrier taping enable high-density PCB placement and automated assembly.
• AEC‑Q200 Qualified: Recognized qualification for applications requiring documented component reliability across temperature and stress conditions.
• Lead‑Free Reflow Compatibility: Designed for lead‑free assembly processes up to a 260°C peak per datasheet guidance.
