CG21AS26F474MRTR1 Datasheet, PDF (1/2 Pages) AVX Corporation – Radial Leaded CapGuard

Radial Leaded CapGuard™
Varistor/Capacitor Combination for EMI/Surge Suppression
GENERAL DESCRIPTION
AVX’s radial leaded CapGuard™ products are designed to provide both transient
voltage protection and EMI/RFI suppression for electronic circuits. CapGuards™ are
ideally suited to filter out EMI/RFI noise generated by switch mode power supplies or
motors on DC lines or I/O lines in electronic circuits. With multilayer varistor (MLV)
utilized in CapGuard product, effective transient voltage protection is achieved to
protect sensitive electronics from high voltage transients. The capacitor, on the other
hand, absorbs high frequency noise on the line. The MLCC capacitors are designed
with temperature stable X7R dielectric, allowing for wide temperature use with good
capacitance stability.
