PCR1D561MCL1GS

The PCR1D561MCL1GS is a conductive polymer aluminum solid electrolytic surface-mount capacitor designed for high-reliability power applications. As an SMD, low-ESR capacitor with high ripple-current capability and extended high-temperature life, it is suited for demanding environments including automotive and industrial power electronics.

Key value propositions include low ESR (20 mΩ at 100 kHz), high ripple current handling (up to 3.1 A at 100 kHz), long life at elevated temperature (4000 hours at 125 °C) and compatibility with lead‑free reflow processes (260 °C peak).

Key Features

• Electrical Performance Low equivalent series resistance of 20 mΩ (100 kHz) combined with 560 µF capacitance and ±20% tolerance provides effective bulk energy storage and low-loss filtering on power rails.
• High Ripple Current Rated ripple current of 1.55 A at 120 Hz and 3.1 A at 100 kHz enables reliable smoothing and decoupling in switching regulator and power supply applications.
• High-Temperature Endurance Qualified for 4000 hours at 125 °C; endurance specifications include capacitance change within ±20% and ESR maintained within specified multipliers after the test.
• Automotive-Grade Reliability AEC‑Q200 qualification and specified ESR after endurance at −40 °C support use in regulated, high‑reliability systems.
• SMD Package & Reflow Compatibility Surface-mount radial can construction designed for lead-free reflow soldering with a 260 °C peak; specified soldering profile and pre‑heat requirements are provided.
• Wide Operating Temperature Rated for −55 °C to +125 °C, accommodating a broad range of thermal environments.
• Compliance RoHS compliant (2011/65/EU, (EU)2015/863) for regulatory and environmental requirements.
• Mechanical/PCB Footprint Compact dimensions (L: 1 cm × D: 1 cm) with a recommended land size of 1.03 cm × 1.03 cm for consistent PCB layout and assembly.

Typical Applications

• Automotive power modules: Use in ECUs and power distribution modules where AEC‑Q200 qualification and high-temperature endurance are required for stable power filtering.
• DC–DC converter outputs: Low ESR and high ripple-current capacity make this part suitable for output filtering on buck/boost converters in both automotive and industrial systems.
• Infotainment and telematics power rails: Bulk decoupling and transient smoothing for audio amplifiers, communication modules and supply rails exposed to elevated temperatures.
• Industrial power electronics: Energy storage and smoothing in compact SMD form for controllers and embedded power supplies operating across −55 °C to +125 °C.

Unique Advantages

• Low-loss power filtering: 20 mΩ ESR at 100 kHz reduces power dissipation and improves regulator stability in high-frequency applications.
• High ripple handling: 3.1 A ripple current capability at 100 kHz supports demanding switching regulator outputs and reduces the number of capacitors needed on the rail.
• Extended high‑temperature lifetime: 4000 hours at 125 °C provides predictable aging and longer service intervals for thermal-stressed designs.
• Automotive-grade assurance: AEC‑Q200 qualification and specified ESR behavior after endurance and low-temperature testing help simplify reliability validation for vehicle systems.
• Assembly-ready SMD format: Designed for lead‑free reflow (260 °C peak) with specified soldering profiles to streamline automated PCB assembly.
• Regulatory compliance: RoHS conformity supports deployment in regulated markets without additional material restrictions.
