PCH1V680MCL4GS

The PCH1V680MCL4GS is a conductive polymer aluminum solid electrolytic chip capacitor in Nichicon’s PCH series. It is a polarized surface-mount device specified at 68 µF and 35 V, designed for applications that require low ESR and high ripple-current capability.

Targeted use cases include automotive and other high-temperature electronics where long-term reliability and stability across a wide temperature range are required. Key value propositions include low ESR (31 mΩ at 100 kHz), high ripple current capability, AEC‑Q200 qualification, and a long endurance rating of 4000 hours at 135°C.

Key Features

• Capacitance & Voltage — Rated at 68 µF and 35 V, with a tolerance of ±20% at 120 Hz, 20°C.
• Low ESR — Equivalent series resistance of 31 mΩ measured at 100 kHz, enabling improved high-frequency decoupling and power stability.
• High ripple-current capability — Rated ripple current of 1.1 A at 100 kHz and 550 mA at 120 Hz for handling dynamic load currents.
• Extended high-temperature endurance — Long life: 4000 hours at 135°C with defined post‑endurance limits for capacitance, tan δ, ESR, and leakage current.
• Wide operating temperature range — Specified for −55°C to +135°C for operation across extreme environments.
• Surface-mount package — Chip-type SMD construction; case dimensions L 8 × D 6.3 mm and recommended land size 6.6 × 6.6 mm for compact PCB placement.
• Assembly compatibility — Compatible with lead‑free reflow soldering up to 260°C peak (reflow conditions supported as specified in the datasheet).
• Automotive-grade qualification — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and −55°C to +135°C rating make this capacitor suitable for automotive control modules and power electronics requiring reliable operation in harsh environments.
• High-temperature systems — Long endurance at 135°C and defined ESR behavior after endurance testing support use in electronics exposed to sustained high temperatures.
• Compact surface-mount power stages — Small 8 × 6.3 mm chip package and low ESR make it suitable for space-constrained SMD power decoupling and local energy storage.

Unique Advantages

• Low ESR for improved power integrity — 31 mΩ at 100 kHz reduces voltage ripple and improves regulator stability in high-frequency circuits.
• High ripple current capability — Rated ripple current values at both low and high frequencies support dynamic loads and reduce heating under AC stress.
• Long high-temperature life — 4000 hours at 135°C provides a quantifiable endurance metric for designs requiring prolonged elevated-temperature operation.
• Automotive-ready qualification — AEC‑Q200 qualification supports use in designs that require automotive-grade component sourcing and reliability traceability.
• SMD convenience with reflow compatibility — Chip-type SMD form factor and compliance with 260°C lead‑free reflow make assembly straightforward for modern PCB processes.
• Wide temperature range — −55°C to +135°C operating range covers a broad set of environmental conditions without additional derating guidance included here.
