PCH1V151MCL6GS

The PCH1V151MCL6GS is a conductive polymer aluminum solid electrolytic chip capacitor in Nichicon's PCH series, designed for surface-mount PCB power applications. As an SMD, polar capacitor with a 150 µF capacitance at 35 V, it delivers low equivalent series resistance (ESR) and high ripple-current capability in a compact package.

Engineered for demanding environments, this AEC-Q200 qualified device offers long-term reliability with a rated lifetime of 4000 hours at 135 °C and an operating temperature range from −55 °C to +135 °C, making it suitable for automotive and other high-reliability electronic systems.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance rated at 35 V for bulk energy storage and decoupling in power rails.
• Low ESR — 22 mΩ ESR measured at 100 kHz, supporting lower loss and improved voltage stability under dynamic loads.
• High Ripple Current — 2.2 A at 100 kHz (2.2 A high-frequency rating) and 1.1 A at 120 Hz (low-frequency rating), enabling effective handling of switching currents.
• High-Temperature Endurance — Rated life of 4000 hours at 135 °C; endurance specifications ensure capacitance, tan δ and ESR remain within defined limits after stress.
• Wide Temperature Range — Operates from −55 °C to +135 °C, with impedance stability specified down to −55 °C.
• SMD Package & Reflow Compatible — Chip-type SMD in a compact radial can footprint (L: 1.0 cm × D: 0.8 cm) with lead-free reflow soldering compatibility up to a 260 °C peak.
• AEC-Q200 Qualified & RoHS Compliant — Designed and manufactured to meet automotive-grade stress requirements and RoHS environmental directives.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and operation to +135 °C make this capacitor suitable for in-vehicle power systems and control modules that demand long-term thermal endurance.
• Power Supply Filtering — 150 µF capacitance combined with 22 mΩ ESR and high ripple-current ratings supports smoothing and decoupling in DC–DC converters and power rails.
• High-Temperature Embedded Systems — Rated lifetime of 4000 hours at 135 °C and wide temperature range support applications exposed to elevated operating temperatures.

Unique Advantages

• Reliability in Elevated Temperatures: 4000-hour life at 135 °C ensures sustained capacitance and controlled ESR/tan δ changes for long-term use in hot environments.
• High-Frequency Performance: Low ESR specified at 100 kHz and high ripple-current capability reduce heating and improve efficiency in switching power stages.
• Automotive-Grade Qualification: AEC-Q200 qualification provides assurance for designers targeting automotive and other high-reliability markets.
• Assembly-Friendly SMD Form Factor: Chip-type SMD with lead-free reflow compatibility (260 °C peak) simplifies placement and reflow processes on automated production lines.
• Regulatory Compliance: RoHS compliance supports environmental and product-compliance requirements.
• Compact Footprint: Small L × D dimensions (1.0 cm × 0.8 cm) and a surface-mount land size of 8.3 mm × 8.3 mm allow dense PCB layouts.
