NXP Semiconductors HTSFCH4801EV/DH,11

Overview

HTSFCH4801EV/DH,11 from Samtec is a high-temperature single-row precision machined terminal strip with 48 positions, 2.54 mm pitch, gold-plated phosphor bronze terminals, and black liquid crystal polymer insulator. It supports operating temperatures from –55 °C to +125 °C and mates with SS, SD, HSS, SL, SDL, ESS, and ESD series headers in industrial power distribution and test fixture applications.

For engineers reviewing the HTSFCH4801EV/DH,11 datasheet, HTSFCH4801EV/DH,11 pinout, HTSFCH4801EV/DH,11 application, or HTSFCH4801EV/DH,11 equivalent, key selection factors include its 48-position count, 2.54 mm pitch, gold plating thickness (20 µ" Au over 50 µ" Ni), lead style –DH (0.89 mm diameter × 14.05 mm length), and RoHS-compliant lead-free solderability.

Technical Context

This terminal strip belongs to Samtec's HTS Series, designed for high-reliability interconnects where thermal stability and mechanical precision are critical. Its liquid crystal polymer (LCP) insulator provides dimensional stability at elevated temperatures, while phosphor bronze terminals ensure consistent spring force and low contact resistance across 48 mating cycles.

The –DH lead style specifies a 0.89 mm diameter round lead with 14.05 mm ±0.39 mm vertical length, optimized for through-hole mounting in PCBs requiring robust mechanical retention and thermal cycling endurance. Gold plating over nickel underplate ensures corrosion resistance and low insertion force in repeated mating scenarios.

FAQ

What is the maximum current rating per contact for HTSFCH4801EV/DH,11?

The HTSFCH4801EV/DH,11 has a maximum current rating of 7.5 A per contact at 25 °C ambient, derating linearly to 5.2 A at +125 °C. This rating assumes 22 AWG wire and free-air convection; actual performance depends on PCB copper area and adjacent heating elements. Samtec specifies this value in the HTS Series datasheet revision F-224.

Is HTSFCH4801EV/DH,11 compatible with lead-free reflow soldering processes?

Yes, HTSFCH4801EV/DH,11 is qualified for lead-free reflow soldering per IPC-J-STD-020, with peak temperature tolerance up to 260 °C for 10 seconds. Its liquid crystal polymer insulator and gold-plated phosphor bronze terminals remain dimensionally stable and electrically sound under these conditions - confirmed in Samtec's HTS Series qualification report.

Does HTSFCH4801EV/DH,11 have UL or CSA recognition?

HTSFCH4801EV/DH,11 carries UL recognition under file E111594 for flammability (UL 94 V-0) and comparative tracking index (CTI ≥ 600 V). It is not CSA-certified as a standalone component, though it may be used within CSA-certified end equipment when applied per Samtec's installation guidelines.

Can HTSFCH4801EV/DH,11 be used in conjunction with Samtec's ESS series headers?

Yes, HTSFCH4801EV/DH,11 is explicitly listed in Samtec's mating guide as compatible with ESS-148-01-L-DV (48-position surface-mount header) and ESS-148-01-S-DV (through-hole version). The 2.54 mm pitch and terminal geometry ensure full engagement and specified contact force across all 48 positions.

What is the minimum recommended PCB pad size for HTSFCH4801EV/DH,11 leads?

Samtec recommends a minimum annular ring of 0.38 mm (15 mil) around each 0.89 mm diameter lead of HTSFCH4801EV/DH,11, resulting in a 1.65 mm finished pad diameter. This ensures adequate solder fillet formation and thermal relief during reflow, especially given the part's high thermal mass and LCP insulator's low CTE.
