B. Tolerances = 0.00 0.01 inch.
0.000 0.005 inch.
C. HD1-40 and HD3-40 models are normally supplied with a flat base plate. To
specify an HD1-40 or HD3-40 model with the optional cross-cut heat sink,
add the letter “H” to the end of the part number (e.g., HD1-40-5AH).
D. Module weight:
HD1-30, HD3-30, HD1-40 and HD3-40, no heat sink = 4 oz. (113g).
HD1-40 and HD3-40 with cross-cut heat sink = 5 oz. (142g).

Notes
1. Use of an external input line fuse is recommended:
For HD1-30 and HD3-30 models with 12V input, use an
6.0A/125V slow-blow fuse.
2. Peak-to-peak and RMS metering equipment must have a
20 MHz frequency response with probes and cables that
maintain a frequency response of 20 Hz to 20 MHz.
Output ripple and spikes are measured directly at the out-
put terminals of the dc-to-dc converter with a 0.1 µF
ceramic capacitor. The instruments’ probe ground bands
must make direct contact with the output return pin or the
common terminal of the converter in order to prevent erro-
neous noise measurements.
Output Adjustment
For HD1-30 and HD3-30 models with 24V input, use a
3.0A/125V slow-blow fuse.
For HD1-30 and HD3-30 models with 48V input, use a
2.0A/125V slow-blow fuse.
For HD1-40 and HD3-40 models with 12V input, use an
8.0A/125V slow-blow fuse.
For HD1-40 and HD3-40 models with 24V input, use a
4.0A/125V slow-blow fuse.
3. All measurements are at nominal input, full load, and
+25°C unless otherwise specified.
For HD1-40 and HD3-40 models with 48V input, use a
2.0A/125V slow-blow fuse.
4. MTBF is calculated using the parts stress method in MIL-
HDBK 217F (ground benign, T = +25°C).
