PLS0J331MDL4

The PLS0J331MDL4 is a radial-lead conductive polymer aluminum solid electrolytic capacitor offering 330 µF capacitance at a 6.3 V rating. It combines ultra-low ESR and high ripple-current capability with long-life endurance for demanding power-filtering and decoupling roles in compact electronic assemblies.

Key electrical and mechanical characteristics include an ESR of 20 mΩ at 20°C/100 kHz, low-frequency ripple current of 1.5 A (120 Hz) and high-frequency ripple current of 3 A (100 kHz), a wide operating temperature range of −55°C to +105°C, and a rated load life of 5000 hours at 105°C.

Key Features

• Conductive polymer construction Solid conductive polymer electrolyte for stable performance and low ESR compared with traditional electrolytes.
• Low Equivalent Series Resistance (ESR) ESR specified at 20 mΩ (20°C, 100 kHz) to support efficient high-frequency operation and reduced loss.
• High ripple-current capacity Rated for 1.5 A at 120 Hz and 3 A at 100 kHz, enabling effective smoothing and decoupling in power circuits.
• Long-life endurance Load life specified at 5000 hours at 105°C, maintaining capacitance, tan δ and ESR within defined limits after endurance testing.
• Wide temperature range Operates from −55°C to +105°C for reliable performance across harsh thermal environments.
• Compact radial can package Size φ6.3 × 10.5 mm with 2.5 mm lead spacing (±0.5 mm) for space-efficient through-hole mounting.
• RoHS compliant Manufactured to meet RoHS requirements.

Typical Applications

• Power supply filtering Use for bulk and output filtering where high ripple current handling and low ESR improve voltage stability and thermal performance.
• Decoupling in compact electronics Small φ6.3 can and radial-lead format suit tight through-hole layouts requiring robust decoupling at both low and high frequencies.
• Industrial and commercial control electronics Wide operating temperature and long-life rating make it suitable for control modules and power management subsystems.

Unique Advantages

• Efficient high-frequency performance: Low ESR at 100 kHz (20 mΩ) and a 3 A high-frequency ripple rating help suppress switching noise and improve regulator stability.
• Durable under elevated temperature: 5000-hour life at 105°C provides predictable long-term behavior in thermally stressed designs.
• Small footprint for through-hole boards: φ6.3 × 10.5 mm package with 2.5 mm lead spacing enables dense PCB layouts without sacrificing ripple capability.
• Broad temperature capability: −55°C to +105°C operating range supports applications across a wide range of environmental conditions.
• Regulatory compliance: RoHS-compliant construction supports lead-free manufacturing practices.
