RTCA/DO-160E SECTION 22 COMPLIANCE MATRIX

(LIGHTNING INDUCED TRANSIENT SUSCEPTIBILITY)

The following table shows the RTCA/DO-160 Section 22 requirements that have been met* by a stand-alone setup comprised of:

- MQME-28-P (or –T) Filter

- MQFL-28-05S DC/DC Converter

- Resistive Load

- Metal Chassis Plane

- Unshielded Power Cable Bundle

* Requirement is deemed to have been met as long as transient deviations in the converter’s output voltage remain within ±10% of

its initial value.

† For these waveforms at Level 3 and above, an external transient suppressor of sufficient energy rating must placed across the filter’s

input pins to keep the differential transient input voltage below +200V/-50V. Negative polarity waveforms may cause power flow to

the converter to be interrupted long enough to cause a graceful shutdown and restart of the converter. Also, the reverse voltage pro-

tection feature of the -T filter is required to protect the converter (but not the filter) from negative polarity waveform.

** For this waveform at a Level 4 and above, external transient suppressors of sufficient energy rating must be added between the fil-

ter’s input power pins and its case to keep the common-mode transient input voltage below +800V.
