MRAAY

MRAAY appears exposed to high-reliability MLCCs and power magnetics used in server and industrial power supplies, with a smaller handset component exposure tied to speculative MEMS micropump reports. Our current recommendation: buy, driven primarily by potential expansion of server MLCC TAM from AI/server infrastructure demand over the next 6–12 months.

Recent proof-backed thesis calls

Three recent thematic calls: (1) MLCC market sizing and server MLCC demand growth (source: social post asserting a ~$15B MLCC market and ~$1.3B server MLCC segment in 2025); (2) an arXiv paper proposing a fully automated resonant core-loss measurement system for sub‑MHz magnetics that could speed magnetics development cycles if commercialized; (3) speculative reports that Huawei’s Kirin may use a MEMS micropump for active cooling, which is unverified.

Paper proposes a fully automated resonant core-loss measurement setup for sub‑MHz magnetics using digitally controlled switched-capacitor sequences plus onboard signal processing, replacing manual tuning + heavy FFT workflows. If commercialized, it reduces magnetics characterization time (1000+ points/20s) and labor, potentially accelerating development cycles for high‑frequency power magnetics used in EV/inverter, data-center/AI power, and industrial supplies. Near-term investability hinges on

Post claims the MLCC market is ~$15B, with server MLCCs ~$1.3B in 2025 (~$600M AI servers, ~$700M general servers). It asserts AI-server MLCC demand is growing at 80%+ CAGR and that general-server MLCC demand will also grow (details truncated). If true, this is a demand-growth signal for suppliers of high-reliability/automotive/industrial MLCCs and related passive-component ecosystems.

Post speculates Huawei’s Kirin chipset may include a MEMS micropump for active cooling, implying a potential smartphone thermal-management breakthrough and better sustained performance. The information is unverified and lacks supplier/part details, so tradability is limited.

Current stance

Recommendation: buy. Primary conviction is that AI and server infrastructure demand will lift high-reliability MLCC suppliers over the next 6–12 months. Secondary support comes from potential acceleration of magnetics development cycles if automated measurement systems are commercialized. A speculative handset-cooling pathway (MEMS micropump) is noted but unverified and lower conviction.
