- Review of available part information (from the project)
- MPN: TY-250P
- Manufacturer: Triad Magnetics (noted in project description)
- Designator Prefix: T
- Package: Not set in project properties
- Pin count (as currently represented in the schematic): 7 “connection points” labeled 2, 3, 4, 5, 6, 7, 8; no nets defined
- Datasheet property: Not present
- Datasheet URL
- Official datasheet: Datasheet
- I can add/update the project property ‘Datasheet’ to the above URL now.
- Datasheet extraction and summary (Triad Magnetics TY-250P)
- Primary impedance: 1000 Ω CT
- Secondary impedance: 1000 Ω CT / 250 Ω
- Output: 20 mW
- Primary DC unbalance: 4 mA
- Frequency response: +1 dB from 20 Hz to 20,000 Hz
- Insertion loss @ 1 kHz: < 2.8 dB
- DCR: Primary (2–4) 172 Ω nominal; Secondary (5–8, with 6–7 tied) 172 Ω nominal
- Turns ratio options:
- 1:1 when 6 & 7 are tied
- 2:1 when 5 is tied to 6 and 7 is tied to 8
- Additional limits stated with optional impedances: input voltage ≤ 4.2 Vrms and current ≤ 7 mA
- Dielectric strength (primary-to-secondary): 1500 V
- Operating temperature range: -40°C to +105°C
- Dielectric strength: 1500 V primary-to-secondary (also listed in electrical characteristics)
- Physical pins indicated as 1 through 8 (bottom view shown)
- Primary winding referenced between pins 2 and 4 (CT implied in “1000 Ω CT” spec)
- Secondary winding referenced between pins 5 and 8; configurations:
- 1:1 ratio when pins 6 and 7 are tied together
- 2:1 ratio when 5 is tied to 6 and 7 is tied to 8
- DCR callouts:
- Primary (2–4) 172 Ω nominal
- Secondary (5–8, with 6–7 tied) 172 Ω nominal
- Lead size: 0.025 SQ (8 PLCS)
- Overall maxima shown: 0.900 MAX, 0.800 MAX, 0.770 MAX, 0.700 MAX
- Body/lead spacings called out:
- 0.520 ± 0.020
- 0.200 ± 0.020 (5 PLCS)
- 0.150 ± 0.020
- 0.040
- Bottom view is provided with pin placement diagram
- Note: The drawing provides all necessary geometry to derive an 8-pad footprint; please refer to the original drawing in the datasheet for exact dimensional context and units.
- Audio-range operation: 20 Hz to 20 kHz
- Applications: line matching, telephone coupling, pulse trigger, driver, interstage, input/output isolation
- Multiple connection options to realize 1:1 or 2:1 behavior
- RoHS 3 compliant (2015/863/EU)
- Cross-check: symbol and footprint vs datasheet
- Observed: 7 connection points labeled 2, 3, 4, 5, 6, 7, 8; no pin “1” is represented.
- Datasheet: Shows eight physical pins (1–8).
- Flag: Mismatch — missing pin 1 in the symbol. This can cause incorrect pin mapping, documentation errors, and assembly/orientation ambiguity.
- Observed: A default footprint exists with 7 pads; pad numbering not visible/defined; no placement geometry verified.
- Datasheet: Requires 8 pins/leads with specific spacing (0.025 SQ leads, “0.200 ± 0.020” spacings in 5 places, and additional dimensional constraints).
- Flags:
- Pin count mismatch — 7 pads vs required 8. This will cause board failure (one lead unconnected) and assembly issues.
- Pad numbering undefined — must match 1–8 per bottom-view orientation in datasheet to ensure correct connectivity.
- Dimensional conformity unverified — pad pitch, hole size and body clearances must follow the drawing (e.g., 0.025 SQ leads suggest through-hole pads sized accordingly; the drawing includes a “0.040” dimension that likely relates to hole diameter, but confirm directly from the drawing context).
- Update the schematic symbol to include all 8 pins with correct numbering (1–8) and groupings reflecting primary (2–4, CT implied) and secondary (5–8) connections.
- Define the 1:1 and 2:1 tie options (6–7 tied for 1:1; 5–6 and 7–8 tied for 2:1) in the symbol notes or pin function descriptions.
- Replace the footprint with an 8-pad through-hole pattern matching the datasheet’s bottom-view orientation, pad/hole sizes, and spacings.
- Assign pad numbers 1–8 exactly as shown in the datasheet to prevent assembly and test errors.
- Attach the datasheet URL to the project properties.
- Fix the symbol (add the missing pin 1 and proper numbering).
- Replace the footprint with an 8-pad pattern per the datasheet drawing.
