High Temperature MLCC for Aerospace Electronics in Morocco: Aerospace Exports Rose 22.3 Percent in Nine Months, and Venatech Supplies 128 Walsin 150 °C HT Parts

Morocco’s aerospace exports rose 22.3 percent to 26.2 billion dirhams in the first nine months of 2026, and the Casablanca cluster now builds wiring systems as well as assemblies. For the high temperature MLCC that electronics near heat sources need, Venatech, Walsin’s authorised distributor in Hong Kong, supplies 128 Walsin HT-series parts rated to 150 degrees C.

Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for engineers and buyers at aerospace electrical, wiring, test-equipment and industrial electronics suppliers in Casablanca, Nouaceur, Midparc and Tangier. Walsin Technology (Walsin) is the line we are authorised for. The Walsin figures come from our MLCC export, 09_High_Temperature_HT.xlsx and the combined file of 23,601 distinct MLCC part numbers, re-measured on 11 November 2026, and our ready stock list as at 23 September 2026. Every part number below is real.

How fast are Morocco’s aerospace exports growing?

By more than a fifth in nine months. The Rio Times reported on 1 November 2026, citing the Office des Changes, that Morocco’s aerospace exports reached 26.2 billion dirhams (about 2.7 billion US dollars) in January to September 2026, up 22.3 percent from 21.4 billion dirhams a year earlier.

The Rio Times report, read on 11 November 2026, splits the total into assembly, up 27.5 percent to 18.0 billion dirhams, and electrical wiring interconnection systems, up 12 percent to 8.1 billion dirhams. It cites Midparc’s chief executive for an unofficial count of about 155 aerospace companies, and notes that Curtiss-Wright signed a memorandum of understanding on 21 July 2026 for a surface-treatment plant in Greater Casablanca. These are the publication’s figures, not ours.

Why would a Moroccan aerospace supplier need a high temperature MLCC?

Because standard X7R stops at 125 degrees C. Electronics placed near engines, brakes, actuators and hydraulic systems, sensor conditioning boards inside hot enclosures, and the test rigs that cycle parts through heat all ask capacitors to work above the 125 degree C limit of X7R; the X8 dielectric codes extend that to 150 degrees C.

The two codes behave differently. X8R is a class II dielectric that keeps capacitance within plus or minus 15 percent from minus 55 to 150 degrees C, so it suits decoupling and filtering where you need nanofarads. X8G is a class I, NP0-like dielectric that stays almost flat with temperature, so it suits timing, resonant and sensor-interface circuits. Our post on high temperature MLCC to 150 C: the HT series covers both in more depth.

How many Walsin high temperature MLCC can Venatech supply?

128 HT-series part numbers, and 235 with an X8 code in total. We counted 128 Walsin HT-series MLCC in our export: 102 X8G and 26 X8R, in 0402, 0603, 0805, 1206 and 1210; across all series, 235 Walsin MLCC carry an X8 code, adding 104 X8G microwave parts and 3 X8G automotive parts.

The X8R parts are all 50 V and run from 100 pF to 100 nF; the highest value is HT31R104K500 in 1206. The X8G parts run from 1.0 pF to 15 nF, 35 at 50 V and 67 at 100 V. Two HT lines were on our Hong Kong shelf as at 23 September 2026, both X8G in 0805.

In the code, the letter after the size gives the dielectric: R is X8R and G is X8G in the HT series, while B is X7R elsewhere. Our guide to how to read a Walsin MLCC part number covers the rest.

What should an aerospace team check before using a Walsin HT part?

Qualification scope first, then derating. We checked our export for all 128 HT parts: it lists size, dielectric, value, tolerance and voltage, and it does not describe any aerospace qualification, so treat these as commercial high-temperature parts and run them through your programme’s own qualification and approval process.

On the engineering side, three points matter. First, X8R loses capacitance with DC bias like any class II dielectric, and more so near its temperature limit, so measure at your rail voltage and hottest point. Second, life at 150 degrees C is shorter than at 85 degrees C; read the endurance test conditions on Walsin’s datasheet. Third, solder joints and board materials must survive the same temperature as the capacitor. For ground support and test equipment, where the qualification burden is lighter, the HT series is often a direct fit.

How can Venatech help a Casablanca aerospace supplier?

How Venatech helps is to cross your high-temperature list to an authorised Walsin source quickly. VenaMatch at /cross-reference/ decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, returning every field marked match or mismatch, so a 150 degree C capacitor from another brand comes back with its Walsin HT candidate and dielectric side by side.

Upload a full BOM at /bom/, browse the MLCC range, check the dated ready stock list (a snapshot as at 23 September 2026, never live-synced) and request a quote through the site. We serve from Hong Kong in small lots with fast quotes, hold no office in Morocco, hold no AS9100 certificate, give no legal, customs, export-control or conformity advice, and leave qualification with you.
