Aishi Radial Lead Capacitors

Radial capacitors are used in consumer electronics, power supplies, audio equipment, LED drivers, and industrial controls. They are ideal for applications requiring compact size and cost-effective solutions.

For general-purpose applications with moderate capacitance requirements, radial capacitors offer the best cost-performance ratio.

RS series is the standard radial capacitor for general applications. RH series offers higher temperature ratings (up to 125C) and longer lifetime. RT series features low impedance for high-frequency applications.

Use RS series for standard applications up to 85C. Use RH series for high-temperature applications. Use RT series for switching power supplies.

Standard radial capacitors are rated for 2,000 to 10,000 hours at 85C or 105C. Lifetime can be extended significantly with proper derating and lower operating temperatures following the Arrhenius equation.

For extended lifetime, operate at lower temperatures and use voltage derating. Calculate expected lifetime using the Arrhenius equation.

Yes, Aishi radial capacitors are widely used in LED drivers, particularly for output filtering. Select capacitors with appropriate lifetime ratings and ripple current capability for your LED application.

For LED drivers, select capacitors with 8,000+ hour lifetime ratings and sufficient ripple current capability. Consider RH series for high-temperature environments.

Ripple current ratings for Aishi radial capacitors range from 0.1A to 2.5A depending on capacitance, voltage rating, and case size. Higher capacitance values and larger case sizes typically offer higher ripple current capability. The ripple current rating is specified at 100-120Hz and must be derated for higher frequencies. Temperature also affects ripple current capability - ratings are specified at 85°C or 105°C, and capability increases at lower temperatures. Always select capacitors with ripple current ratings at least 1.5x your application's calculated ripple current to ensure reliable operation and long lifetime.

Select capacitors with ripple current ratings at least 1.5x your application requirements. Consider frequency and temperature derating for accurate selection.

Yes, Aishi offers low-profile radial capacitors with reduced height specifically designed for space-constrained applications. These low-profile versions maintain the same electrical performance as standard capacitors while offering reduced diameter-to-height ratios. They are ideal for slim LED drivers, compact power supplies, and applications with height restrictions. The low-profile design allows for more compact product designs without sacrificing reliability or performance. Available in various capacitance and voltage ratings to meet different application requirements.

For height-restricted applications, specify low-profile versions with reduced diameter-to-height ratios while maintaining required electrical specifications.
