Chip Ceramic Filters
for Communication
Surface Mount Ceramic Filters
for Communication (Murata CFUCG Compatible)
Preview
Token chip ceramic filters LTC455/450 U/W series for communication (Compatible to Murata CFUCG series)
comprises small, high performance, thin (4.0mm) consisting of 4 ceramic elements. Their innovative construction
is perfect for shrinking mobile communication products such as pocket pagers and cellular phones.
The surface mount LTC455/450 U/W series for AM use is one of the most recommendable intermediate filters,
having such distinctive features as high selectivity, high stability and adjustment-free operation. Additionally its
easy matching with IC helps create an easy circuit design.
With dimensions (7.5 x 6.0 mm) and 4.0 mm low profile, the LTC455/450 U/W filters have a small mounting
area enabling flexible PCB design and are suitable for automatic placers. Standard Center Frequency is 455kHz
with tolerance ±1.5 and 450kHz is also available. Pass Band Ripple (dB) max is 2db, Input / Output Impedance is
1000Ω and 1500Ω.
Custom parts are available on request. Token will also produce devices outside these specifications to meet
specific customer requirements, please contact our sales for more information.
Features
- They are slim, at only 4.0mm max. thickness, and have a small mounting area enabling flexible PCB design.
- Operating temperature range: -20°C to +80°C.
- Can be reflow soldered and withstand washing.
- The bandwidth ranges from D to G.
- Mountable by automatic placers.
