MIL-PRF-49470 Caps Now Available from Johanson

MIL-PRF-49470 Caps Now Available from Johanson

Johanson is now approved to produce MIL-PRF-49470 series stacked capacitors. We are approved for Case Sizes 3, 4, and 5 in 500V rating. MIL-PRF-49470 approval is often required by the larger MIL OEMs to participate in their capacitor buy even when they don't specifically purchase 49470 caps. This approval should be a door opener at accounts such as BAE, Lockheed Martin, Northrup Grumman, Raytheon and other major players in the MIL markets.

SPICE Models Released for EMI Filters and Power Bypass Products

SPICE Models Released for EMI Filters and Power Bypass Products

Johanson Dielectrics is pleased to announce the release of SPICE models for its X2Y series of components. This release contains specific SPICE models for both components when used in EMI Filtering or Power Bypass applications, and two illustrative explanations. SPICE models allow circuit designers to run circuit simulations prior to actual production of hardware, which is a frequent request amongst circuit designers. It should be noted that SPICE models do not model EMI performance as this requires highly specialized EMC simulators. Click Here to download the models.

EMI Supression Filter Graph

EMI Supression Filter Available

Johanson EMI Supression Filter Chips feature X2Y's proven, pantented low noise architecture and are one of the most effective EMC filters available on the market today. Features include ultra-low ESL for an ultra-wide filter stop-band, and tightly matched impedance for very low noise-mode conversion. This enables DC power chokes to be replaced with a typical application savings of 50% cost and 80% size reduction.
