Designed for I/O port protection on USB 2.0, IEEE 1394, digital visual interface (DVI) and antenna switches, PESD0402 and 0603 electrostatic discharge (ESD) protection devices are available in popular form factors. The RoHS-compliant devices shunt ESD away from sensitive circuitry in HDTV equipment, printers, laptops, cellular phones and other portable devices.

Utilize advanced thick film technology to provide low capacitance (typically 0.25 pF) for ESD protection in high-speed data transmission applications. The devices perform better than comparable components in transmission line pulse (TLP) testing. Offer lower trigger and clamping voltages than typical polymeric ESD devices, resulting in improved protection of sensitive electronic components. Said to perform better in IEC61000-4-2 testing, especially after multiple hits (up to 1000).

Available in standard EIA sizes 0402 and 0603, with a quad-array in 1206 coming soon. Compatible with standard surface-mount and reflow installation procedures, available in tape and reel packaging.

MMCX, MCX and SMA connectors have been added to the Samtec product line.

Micro-Mini connectors (MMCX) are available as jacks and plugs with a choice of through-hole, surface-mount and edge-mount terminations. A "ganged" variation of the through-hole option is also offered for terminating two, four, six or eight connectors to the board simultaneously (useful in board stacking applications).

Mini connectors (MCX Series) are also available as jacks and plugs with a choice of through-hole, surface-mount and edge-mount terminations. SMA jacks are available with through-hole, edge-mount and panel-mount terminations.

Cable plug terminations are available for all these interfaces, as are custom RF cable assemblies.

The MINI RF switchable connector series is intended for test and accessory use in conjunction with a range of telecommunications, consumer, automotive and industrial equipment.

Measures 2.7 x 2.7 mm and 1.6 mm high; ideal for small devices requiring verification of antenna and circuit performance. Supports signal frequencies up to 6 GHz and incorporates 3-degree misalignment, allowing for angular misalignment when mating sections are engaged.

Available in a Test Port version, to test electronic circuitry (pre-transmitting element), and an Accessory Port version, to test and redirect signals through an external transmitting element.

Durable snap-on interface allows for 100 mating cycles. The cradle interface - present in the Accessory Port version - exceeds 5,000 mating cycles. It corrects misalignment issues that are present in other products on the market.

Offers a robust interconnect, incorporating a split insulator design. With the contacts sandwiched between two insulators, the connector design minimizes the risk of solder flux contamination of the switch. Beryllium copper contacts are used with insulators made of liquid crystal polymer. The shell is copper alloy (phosphorous bronze) with an additional layer of matte tin or gold-over-nickel for the Test Port or Accessories Port versions, respectively.

Allow continuous operation at temperatures from -40 to +85°C. Weighs 0.02 grams.
