TCD
The TCD series are radial lead ceramic capacitors from UCC/NCC. These capacitors have a very low
ESR and impedance which makes these capacitors ideal for filtering switching power supplies and
DC-DC converters. The TCD series has a maximum 250VDC rated voltage making them more
applicable for use in higher voltage power supplies than our ceramic chip capacitors. All of our radial
capacitors with 5mm lead spacing are also available with ammo pack taping.
Refer to Mini-Glossary at the end of the multilayer ceramic capacitors section for additional technical
information and specifications.
