25YD10-R

The 25YD10-R is a ceramic disc EMI suppression capacitor from Vishay, part of the 25Y series. It offers a capacitance of 1000 pF with a tolerance of ±20% and uses a Y5S Class 2 dielectric. The capacitor is safety rated for Class X1 at 400 VAC and Class Y2 at 300 VAC (for lead spacing ≥ 5.5 mm), making it suitable for line-to-line and line-to-ground filtering in AC power applications.

Key electrical specifications include a dissipation factor of 2% maximum at 1 kHz and 1 V, and a minimum insulation resistance of 1000 ΩF. Dielectric strength is 2500 VAC between leads (component test) and 2300 VAC for body insulation. The operating temperature range spans -30°C to +125°C, with a climatic category of 25/125/21 per EN 60068-1.

The capacitor is housed in a radial disc package with straight leads, lead spacing of 6.40 mm, and a diameter of 8.40 mm and height of 11.60 mm. It is designed for through-hole mounting and features a flame-retardant epoxy coating rated UL 94 V-0. The part is RoHS and REACH compliant (unverified) and intended for safety applications such as EMI/RFI suppression in switch-mode power supplies.
