DESCRIPTION

The NTH series of miniature surface mounted

DC-DC Converters employ leadframe

technology and transfer moulding techniques

to bring all of the benefits of IC style

packaging to hybrid circuitry. The component

lead termination of this product range is lead-

free compatible, therefore the converter can

be soldered in a lead-free soldering process.

The devices are fully compatible with

CECC00802 to 280°C which allows them to

be placed and reflowed with IC’s, thus

reducing time and cost in production. Co-

planarity of the lead positions is based upon

IEC 191-6:1990. The devices are suitable for

all applications where high volume

production is envisaged.

1 Calculated using MIL-HDBK-217F with nominal input voltage at full load.

2 See derating curve.

3 12V input types have typically 3% less load regulation change.

4 Supply voltage must be discontinued at the end of the short circuit duration.

5 If components are required in tape and reel format suffix order code with -R, e.g. NTH0505M-R
