TP250MV

Product catalog summary

Description: The TP250MV converter transformers are designed for use with Maxim chipsets to provide isolated RS232 interfaces. They feature controlled turns ratios for consistent performance and toroidal construction to minimize EMI.

Characteristics: Key parameters include primary inductance (0.75-2.5 mH), leakage inductance (35-40 μH), interwinding capacitance (9-12 pF), and primary D.C. resistance (1.4-1.8 Ω). The volt-time product is 50 Vμs.

Order Code Details: The TP250MV is available in a 6 Pin SM package, with options for tube (50 units) or tape & reel (500 units) packaging.

Absolute Maximum Ratings: Operating temperature ranges from -40°C to 85°C, with storage temperatures from -50°C to 125°C. The lead temperature can reach 300°C for 10 seconds, and the peak current is 300mA. Isolation voltage is 4KVDC.

Mechanical Dimensions: All dimensions are in inches with a tolerance of ±0.01 (0.25mm). Pins are on a 0.1 (2.54mm) pitch.

Features: The product is RoHS compliant, supports an industrial temperature range, offers 4KVDC isolation, and has a low profile toroidal construction. It is fully encapsulated and uses UL 94 V-0 package materials.

Part Number Turn Ratio: TP250MV has a 1:1 turn ratio, while TP250MVA1 has a 1:1.2 ratio.

Soldering Information: Pin finish is matte tin, with a peak wave solder temperature of 300°C for 10 seconds and a peak reflow temperature of 220°C.

Tape & Reel Specifications: Tube length is 18.3±0.08 inches (465±2mm), made from antistatic coated clear PVC.
