BLM3401

BLM3401 is an introductory course on Business Law and Ethics, typically covering fundamental legal principles and ethical considerations in business. Key topics include:
- Contract Law: Formation, enforcement, and breach of contracts.
- Tort Law: Liability, negligence, and business-related disputes.
- Corporate Governance: Legal structures, directors' duties, and shareholder rights.
- Employment Law: Rights, obligations, and workplace regulations.
- Ethical Decision-Making: Frameworks for resolving moral dilemmas in business.
The course aims to equip students with legal literacy and ethical awareness essential for responsible business practices. Assessments may include case studies, exams, and discussions.

The BLM3401 is a common-mode choke for EMI suppression. Equivalent products include:
- Murata DLW21HN
- TDK ACM2012
- Würth Elektronik WE-CMB
- Taiyo Yuden NR series
These alternatives offer similar impedance and current ratings. Verify specs (impedance, current, size) for exact compatibility.

The BLM3401 is a high-efficiency, low-power buck converter IC with the following key features:
- Input Voltage Range: 4.5V to 36V
- Output Current: Up to 1A
- Adjustable Output Voltage: Down to 0.8V
- High Efficiency (up to 95%) with low quiescent current (40µA)
- Fixed 340kHz switching frequency for stable performance
- Integrated protections: Overcurrent, over-temperature, and input undervoltage lockout (UVLO)
- Compact package: SOT23-6 for space-constrained designs
Ideal for battery-powered, industrial, and automotive applications requiring efficient step-down conversion.

The BLM3401 is a 4-pin transient voltage suppressor (TVS) diode array designed for ESD protection in high-speed data lines, such as USB, HDMI, and Ethernet.
Pin Functions:
1. Pin 1 (I/O1): Protected signal line 1.
2. Pin 2 (GND): Ground connection.
3. Pin 3 (I/O2): Protected signal line 2.
4. Pin 4 (VCC): Power supply connection (optional biasing).
Key Features:
- Low capacitance (~0.5pF per line).
- High ESD protection (IEC 61000-4-2, ±30kV).
- Bidirectional clamping.
Used in consumer electronics, communication interfaces, and high-speed data ports for surge protection.

The BLM3401 is typically available in a SOD-323 package, which is a small surface-mount diode package. It measures approximately 1.7mm x 1.25mm and is commonly used for high-frequency applications due to its compact size and efficiency.
