Spectrum's New Miniature Hermetic L Circuit Solder-in EMI Filters Improve Insertion Loss
PA – August 17, 2010 – Spectrum Advanced Specialty Products announces the release of a new L circuit EMI filter
designed to provide both inductance and series resistance for superior transient performance. This feed-through
solder-in filter’s miniature case size, .156"OD X .128"ID with body length of .200", for a total overall length of
.715", is ideal for microwave and RF applications where space is an issue but that still require high performance
EMI filtering with low insertion loss.
The new RoHS compliant, hermetically sealed L circuit filter
provides excellent filtering from 10kHz to over 10GHz, with capacitance values from 10pF to 0.033µF and a 10Amp
current rating. Voltage ratings range from 50VDC to 200VDC, with high reliability versions also available. The
filter’s rugged monolithic capacitor construction with a glass seal on one end provides extra protection from
harsh environments, and is also gold plated for gold bonding. The miniature L Circuit adds to Spectrum’s mature
line of miniature feed-thru solder-in filters, which are available in a variety of terminations, sizes and circuit
versions of the miniature L Circuit solder-in filter are available, including a reverse seal and special lead
length and end termination options. Designed to be soldered into a package, bracket or bulkhead, the miniature L
Circuit solder-in filter is perfect for microwave and RF applications such as attenuators, oscillators,
multiplexers, synthesizers, yig filters and amplifiers. Prices range from $1 - $3 per part depending on quantity
and configuration required, and custom inquiries are welcome.
