PCR1V331MCL1GS

The PCR1V331MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package designed for high-reliability power applications. It provides 330 µF capacitance at 35 V with low ESR and high ripple current capability, targeting demanding environments where temperature, ripple and longevity matter.

Designed and qualified for robust operation, this part addresses applications that require high temperature endurance, low-loss filtering and long operational lifetime while supporting lead‑free reflow processes up to 260°C.

Key Features

• Electrical Performance — 330 µF nominal capacitance at 35 V with ±20% tolerance and a low ESR of 16 mOhm measured at 100 kHz, enabling effective high-frequency decoupling and ripple handling.
• High Ripple Current — Rated ripple current of 1.95 A at 120 Hz and 3.9 A at 100 kHz, supporting power stages and converter outputs with significant AC stress.
• Wide Temperature Range — Specified for operation from -55°C to +125°C, retaining impedance characteristics across the range per datasheet limits.
• Long Life & Endurance — Life tested to 4000 hours at 125°C with defined limits for capacitance change, tan δ and ESR after endurance.
• SMD, Reflow-Ready Package — Chip-type SMD can (radial can - SMD) compatible with lead-free reflow soldering; peak reflow temperature supported up to 260°C per soldering profile limits.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and qualification-driven designs.
• Compact Footprint — Package dimensions L: 1.27 × D: 1.00 cm with recommended land size of 1.03 × 1.03 cm for compact board layouts.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification, wide temperature range and long life make this capacitor suitable for power filtering and decoupling in automotive control modules and infotainment power rails.
• Power Supply Filtering — Low ESR and high ripple current ratings enable smoothing and stability in DC‑DC converters, post-regulator bulk filtering and power stage outputs.
• Industrial Power Systems — High temperature endurance and robust endurance characteristics suit industrial controllers and motor drive electronics exposed to elevated ambient temperatures.

Unique Advantages

• Low ESR for improved efficiency: 16 mOhm ESR at 100 kHz reduces losses and voltage ripple in high-frequency circuits.
• High ripple capability: 1.95 A (120 Hz) and 3.9 A (100 kHz) ratings support demanding switching and power conversion applications.
• High-temperature endurance: 4000 hours at 125°C provides predictable long-term performance in hot environments.
• Automotive-grade qualification: AEC-Q200 rating gives confidence for applications requiring supplier qualification and reliability documentation.
• Reflow-compatible assembly: Lead-free reflow process compatibility to 260°C simplifies surface-mount manufacturing flow.
• Regulatory compliance: RoHS conformity ensures suitability for designs constrained by current electronic materials directives.
