Ironwood Electronics has recently introduced a new high performance LCC socket for 0.040" pitch 48 pin Leadless Chip Carrier. The SG-MLF-7039 socket is designed for an 0.563"x0.563"x0.081" package size and operates at bandwidths up to 10 GHz with less than 1dB of insertion loss. The sockets are designed to dissipate up to several watts without extra heat sinking and can handle up to 100 watts with custom heat sink. The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 10 GHz bandwidth on all connections.
The SG-MLF-7039 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is -35C to +100 C. The pin self inductance is 0.15 nH and mutual inductance of 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 amps per pin.
Pricing for the The SG-MLF-7039 is $652 at qty 1; with reduced pricing available depending on quantity required.
