PCH1H181MCL1GS

The PCH1H181MCL1GS is a conductive polymer aluminum solid electrolyte chip capacitor from Nichicon’s PCH series. It delivers 180 µF at a 50 V rating in a compact surface-mount can package optimized for high-temperature and high-reliability designs.

Designed for demanding environments, the device combines low ESR and high ripple-current capability with long-term thermal endurance (4000 hours at 135°C), making it suitable for automotive and other harsh-environment power electronics where durability and performance matter.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for bulk decoupling and energy storage in power rails.
• Low ESR & High Ripple Current: 19 mOhm ESR specified at 100 kHz and ripple current ratings of 2.5 A at 100 kHz (1.25 A at 120 Hz), supporting high-frequency switching and power-stage applications.
• High-Temperature Endurance: Qualified for operation from −55°C to +135°C with an endurance specification of 4000 hours at 135°C, maintaining capacitance and ESR within defined limits after the test.
• SMD Package & Reflow Compatibility: Chip-type radial can SMD package (L: 1.27 cm × D: 1.00 cm) designed for lead-free reflow soldering with a peak temperature up to 260°C.
• Automotive-Grade Qualification: AEC‑Q200 qualified and specified for automotive applications, supporting use in automotive electronic modules.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental requirements.

Typical Applications

• Automotive power electronics: Bulk decoupling and smoothing in control modules and power-supply circuits where AEC‑Q200 qualification and high-temperature endurance are required.
• Power converters and DC‑DC stages: Input/output filtering and energy buffering for switching regulators that demand low ESR and high ripple-current capability at high frequencies.
• Industrial high-temperature systems: Power conditioning in equipment that operates at elevated ambient temperatures, leveraging the 4000-hour life at 135°C.

Unique Advantages

• Extended high‑temperature life: 4000 hours at 135°C provides predictable aging behavior and reliability for thermal-stressed designs.
• Improved power-stage performance: 19 mOhm ESR at 100 kHz and 2.5 A ripple current at 100 kHz reduce losses and support stable operation of high-frequency converters.
• Automotive-ready qualification: AEC‑Q200 qualification enables confident selection for automotive and similarly demanding applications.
• Surface-mount convenience: Chip-type SMD can profile and lead-free 260°C reflow compatibility simplify assembly and support automated manufacturing.
• Compact footprint: Small package (1.27 cm × 1.00 cm) offers high capacitance density for space-constrained boards.
• Regulatory conformity: RoHS compliance aligns the component with common environmental requirements for commercial and automotive products.
